INVENTOR ATTORNEY Patented Nov. 29, 1932 UNITED STATES PATENT OFFICE ROLAND B. BOI/LMAN, CINCINNATI, OHIO, ASSIGNOR TO THE MUNNY MANUFACTUR- ING COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO CREASING APPARATUS Application filed. March 23, 1981'. Serial No. 524,604.

My invention relates to im rovements in textile creasing apparatus. ne of its objects is to provide improved apparatus to readil and advantageously crease trousers and 0t er textile articles. to provide creasing apparatus adapted to be applied without removing the garment. Another object is to provide improved means of assembly and adjustability. Another object is to provide improved means to apply heat to the creasing members. Another object is to provide improved means to prevent injury to the electrical conductors close to where they emerge from the handle. Another object is to provide improved means to limit the degree of separation of the creasing blades and limit the degree of introduction of the textile between the blades. Another object is to rovide improved means to strengthen the blade actuating lever. Another object is to provide for increasing the action of the spring without increasing its weight. My invention also comprises certain details of form and arrangement and combination of components all of which will be fully set forth in the description of the accompanying drawing, in which;

Fig. 6 is a view similar to Fig. 4 illustrat-v ing a modification thereof.

The accompanying drawing illustrates modifications of my improved apparatus in Figs. 1 to 5 of which 15 represents a cylindrical heating member having a handle 16 of heat insulating material. The member 15 is preferably heated by means of gas or electricity. An electrical heating member 17 is preferably introduced into the metal shell 18 compresv of the heating member and-electrical conductors 19 lead thereto through a perforation 5o longitudinally of the handle 16. A coil of Another object is spring wire 51 encircles the conductors 19 close to the end-0f the handle to prevent short or sharp bends in said conductors 19 at this localit The creasing apparatus comprises a sheet orcast metal blade 20 having a semi-circular section 52 in contact with one side of the heating member 15, preferably attached rigidly to the heating member 15, for instance by means of screws 21, and a counterpart blade 22 which has a semi-cylindrical channel 23 adapted to make close engagement with the opposite side of the heater member 15. A split tubular spring 24 preferably provided with stamped ribs 53 engages over the heating member 15 and the edges of its s lit engage the respective blades close to the eating member 15 and serve to hold the two blades yieldingly in contact at the base of said blades close to the heating member 15. The blades 20 and 22 preferably diverge slightly from their base outwardly as shown in Fig. 4;. The edges 25, 26, and 27 of the blades are preferably curved or bent outwardly to promote introduction of the'textile' material between the blades, and to facilitate sliding the blades along over the creased textile material.

The blade 20 is provided with stamped prongs or fingers 54, which extend throughperforations 55, in the blade 22. The free ends 56 of the fingers 54 are turned outwardly and serve to limit the extent to which the dle 16, to thereby cause the blade 22 to rock upon the face. of the heating member 15 against the tension of the spring 24am to thereby separatethe blade 22 from the blade" 20 as indicated in Fig. 5 to facilitate introduction of thetextile material between the blades. As soon as the button 31 is released the spring 24: closes the blades together as shown in Fig. 4. The contact of considerable faces or areas of the blades 20 and 22 with the heating member 15 causes the blades to be readily heated by conduction from the heating member 15 and to maintain said blades at substantially uniform temperatures while in use by compensating for any loss in temperature as fast as such heat losses occur, thereby providing against excessive heat locally and for a substantially continuous use of the creasing apparatus if required.

In order to strengthen and reinforce the arm 30 I preferably stamp raised ribs 57 therein, to thereby enable the blade 22 and arm 30 to be stamped integral and prevent the arm 30 being readily bent or deformed. Also in order to strengthen or stiffen the spring 24, without increasing its weight, annular ribs 53 are formed therein, near opposite ends thereof. Said ribs also enable the edges of the spring 24 to secure a broader and more effective engagement upon the blades 20 and 22.

As illustrated in Fig. 6 the two blades 10 and 41 are united by a cylindrical section 42 which is slipped endwise over a cylindrical heating member 43. The blades 40 and 41 and section 42 have a limited amount of resiliency which enables the blades to be separated sufiiciently to introduce the textile material between the blades, and to cause the blades to press upon and crease the textile material.

One mode of operation is to hold the hem or lower end of one leg of a pair of trousers rigidly by hand or in a metal clip, then grasp the opposite end of the trousers leg in one hand at the point where the crease is to terminate and apply the heated creasing apparatus to an already formed crease, drawing the creasing blades along such crease to reform and strengthen the crease, or if no crease has been formed, then apply the creasing apparatus in heated condition to the locality where the crease is to be formed and thereby form a crease. The opposite trouser leg is then treated in like manner. Greases may thus be formed and firmly set wherever required in textile material. Trousers may thus be readily creased while being worn.

The apparatus herein shown and described is capable of considerable modification within the scope of the claims without departing from the spirit of my invention.

What I claim is:

1. Creasing apparatus comprising a cylindrical heating member having a handle in substantial alignment therewith, a creasing blade attached rigidlv to said heating member and extending radially from said heating member at one side thereof, a creasing blade adjustably attached to said heating member and extending radially from said heating member at one side thereof and movable to and from said stationarily mounted blade, said adjustable creasing blade being provided with an actuating arm extending into position adjacent to sald handle and adapted to be actuated by the hand in which said handle is grasped.

2. Creasmg apparatus comprising a cylindrical heating member a pair of creasing blades extending radially from said heating member at one side of said heating member, said blades being relatively movable, one of said blades being provided with fingers, adjacent to said heating member passing through perforations in the opposite creasing blade and having their free ends turned to limit the relative adjustment of said creasing blades and to limit the degree of introduction of the textile material between said blades.

3. A creasing apparatus, comprising, a cylindrical electrical heater element having a hand hold at one longitudinal end thereof, a pair of creasing blades extending radially from the heater element, one blade rigid therewith and the other hingedly mounted thereon and urged toward the other blade, said hingedly mounted blade having a handle for swinging the same to separate the blades, and means for limiting the depth of introduction of the material between the blades and guarding the same from contact with the heater element.

In testimony whereof I have afixed my signature.
